When the discussion comes as to which scope to buy, some will offer the opinion that the large number of 1054Z users, particularly on this forum, is a major plus. It is instances like this that give those statements credence. Imagine trying to sort out something like this with a more obscure scope. You might well wind up sending it off to the factory concerned it is part of a larger fault. All of these low end scopes are going to have some issues, the question is what to do about it. In this case, probably nothing, but how to come to that conclusion on your own. Dave
